LOCOMOTIVE DRIVING BOX.

Specification of Letters Patent. Patented Apr., 25, i922.-

Application led September 30, 1920. Serial No. 413,802. v f

To all whom t may concern Be it known that I, CEoIL ATHERTON, a

- citizen of the United States, residing at Danville, in the county of Vermilion and State hof Illinois, have invented a new and useful Locomotive Driving Box, of which the followlng is a specification.

This invention relates to bearing boxes,

' and more particularly to the brasses supported therein, and on which the axles of a locomotive operate, it being the primary. object of the invention to provide a brass which ymay be readily and easily removed and replaced, eliminating the necessity of removing thewheels to accomplish the repair of the brasses.

A further object of the invention is to provide a novel means for supporting the brasses within their boxes, the supporting 'means being ,of a construction which may be readily and easily applied by a mechanic, thus obviating the use of machine pressers or the like, in the placing of thesecuring means. y With the foregoing and other objects in view which will appear as the description proceeds, the invention resides inthe combination and arrangement of parts and in the details of construction hereinafter described and claimed, .it being understood that changes in the precise embodiment of the invention4 herein. disclosed, may be made within the'scope of what is claimed, without view of a box showing the brasses as secured .thereinl Figure 2' 'illustratesl a vertical sectional view taken on line 2"-'2 of Figure 1.`

Figure 3 illustrates a detail view of one of the brass clamps, and

Figure 4 illustrates a side elevational view of the key employed in securing`- the sectional brass within the box. .g

Referring to the drawing in detail, the reference character 5. designates a conventional form of locomotive driving box which is provided with the usual cut out portions to accommodate the brass designed to support or engage the axle of alocomotive.

The cut out portion ofthe ,driving box is formed with a shoulder 6 at its respective ends, the shoulders being provideda abutments for the ends of the brass sect ons 7 and 8 respectively, and asshown,- more clearly by Figure 1 of the drawing-fthesec'- tions of the brass haveutheir adjacent edgesr disposed in spaced relation with each other,

and provided with a cut out portion 9` adapted to-register to provide a key-way for the tapering key 10, which is relatively long, the same bein of a length to extend the entire length o? the brass, and as shown, this key is provided with a right angled extremity 11.

Formed in the right angled extremity 11 of-the key 10 is a suitable o pening designed to accommodate the securing bolt 12, which has its threaded extremity ositioned in a suitable threaded opening in'the box 5 asindicated by Figure 1 of the drawing, the bolt 12 being threaded as at 14 and designed to accommodate the adjusting nut 15 and lock'- nut 16, whereby the securing bolt 12l may be positioned to secure the key 10 within the cut out portions of the sections lof the; brassl in a manner to, prevent displacement.

Clampingmembers 17 are secured to the box 5 as by means of the bolts 18, and each4 of these "clamping members is providedvwith a cut out portion 19 adapted to engage over the outer edges of the sections 7. and 8 of the brass to secure the sections within the box 5, and prevent movement thereof.

In order that the sections 7 and 8 will bey properly positioned within the box 5, each of the sections is provided with a circumferential fiange 20 adapted to .abut against the end of the box 5. Thus it will be seen that as the sections 7 and 8 lare positioned within the box, the flange, when the-sections are properly positioned, will engage the end' of the box and restrict movement of the sec` tions. j n .I

If it is desired to replace a brass, it 1s only necessar to remove the key 10 andthe clamp 17, w ereupon the sections :ofthe brass may be removed. Upon removing the brass, bolts-are positioned inthe threaded openings 21, which bolts may be-engaged by any suitable tool to draw the brasses fromy l their positions within the box.

It might be further stated that due tothe construction of the key 10, the right angled portion thereof lies in spaced relation with the bodyportion of the 'box 5 to permit a tool In combination with a locomotive .journal los box, said journal box having a cut out portion, a sectional brass positioned Within the cut out portion, a key having inclined walls adapted to be positioned between the adjacent edges of the sections forming the brass, said key having a right angled apertured extension, a bolt adapted to pass through the aperture of the right angled extension, said bolt having a threaded extremity disposed in a threaded opening of the journal boit7 nuts operating on the opposite end of the bolt for adjusting the key with respect to the .bers having a out reiaeaa journal box, clamping members secured to the journal box, each of said clamping memout portion to accommodate the sections of the brass for holding the sections in their positions of adjustment.

ln testimony that l claim the foregoing as my own, l have hereto affixed my signature in the presence of two witnesses.
